which expression is equivalent to g−m  ÷ gn?   g−m + n  g−m ⋅ n    g−m − n  g−m ÷ n

Let x have probability generating function gx (s) and let un generating function u(s) of the sequence uo, u1, satisfies p(x > n). show that the (1- s)u(s) = 1 - gx(s), whenever the series defining these generating functions converge.
